manifest.walk: special-case match.always() for speed This cuts down the run time of hg files -r . > /dev/null from ~0.850s to ~0.780s on the Firefox repo. Note that manifest.matches() already has the corresponding optimization.

manifest.walk: use return instead of StopIteration in generator Using "return" within a generator is supposedly more Pythonic than raising StopIteration.

archive: look for first visible revision to build repo identity (issue4591) No test for the case where all revisions are hidden because "archive" command aborts if the target revision is null.

largefiles: use common function to build content of .hg_archival.txt This fixes the missing "changessincelatesttag" field introduced by 242d11819c6c.

test-largefiles: verify content of .hg_archival.txt

archive: extract metadata() closure to module-level function This function will be reused in largefiles.

archive: use ctx object consistently to build meta data

templatekw: have {manifest} use ctx.manifestnode() for consistency changeset_printer was updated at f57640bf10d4 to not access changeset by index.

subrepo: use vfs.reljoin instead of os.path.join

subrepo: inline reporelpath into abstractsubrepo._relpath to centralize logic "reporelpath()" is referred only from "abstractsubrepo._relpath()".
